+
### Pytorch
|
79 |
+
|
80 |
+
```py
|
81 |
+
import torch
|
82 |
+
from transformers import HubertModel
|
83 |
+
|
84 |
+
model = HubertModel.from_pretrained("team-lucid/hubert-large-korean")
|
85 |
+
|
86 |
+
wav = torch.ones(1, 16000)
|
87 |
+
outputs = model(wav)
|
88 |
+
print(f"Input: {wav.shape}") # [1, 16000]
|
89 |
+
print(f"Output: {outputs.last_hidden_state.shape}") # [1, 49, 768]
|
90 |
+
```
|
91 |
+
|
92 |
+
### JAX/Flax
|
93 |
+
|
94 |
+
```py
|
95 |
+
import jax.numpy as jnp
|
96 |
+
from transformers import FlaxAutoModel
|
97 |
+
|
98 |
+
model = FlaxAutoModel.from_pretrained("team-lucid/hubert-large-korean", trust_remote_code=True)
|
99 |
+
|
100 |
+
wav = jnp.ones((1, 16000))
|
101 |
+
outputs = model(wav)
|
102 |
+
print(f"Input: {wav.shape}") # [1, 16000]
|
103 |
+
print(f"Output: {outputs.last_hidden_state.shape}") # [1, 49, 768]
